由于postgis端口问题，连接到docker集装箱失败

我的docker容器能够成功构build，但是当我input命令docker-compose build ，会返回以下错误：

 Starting docker_etl_1 ... Starting 1e5f56853e10_1e5f56853e10_1e5f56853e10_docker_postgis_1 ...

这是我的docker-compose.yaml

 version: '2' services: postgis: build: ./postgis volumes: - ../src/main/sql:/sql ports: - "5432:5432" etl: build: ./etl volumes: - ..:/national-voter-file entrypoint: - python3 - /national-voter-file/load/loader.py 

这里是Dockerfile：

 FROM mdillon/postgis:9.5 ENV POSTGRES_DB VOTER RUN mkdir /sql COPY ./dockerResources/z-init-db.sh /docker-entrypoint-initdb.d/ EXPOSE 5432 

Docker ps -a返回：

 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES da74ad97b95c docker_postgis "docker-entrypoint..." About a minute ago Created docker_postgis_1 5872c6e55fe2 docker_etl "python3 /national..." About a minute ago Exited (2) About a minute ago docker_etl_1 

但是，当我尝试rm $(docker ps -qa) ，出现以下错误：

 rm: da74ad97b95c: No such file or directory rm: 5872c6e55fe2: No such file or directory 

我不相信我有另一个容器运行，所以我很困惑的消息Bind for 0.0.0.0:5432 failed: port is already allocated

Answer 1

是否有可能你之前运行过相同的docker-compose，可能失败了，或者至less没有清理这些服务？ 尝试运行docker ps -a来检查是否存在任何已停止的容器。 被停止的集装箱可能会占用港口。 如果是这样，只需使用docker rm $(docker ps -qa)清除它们即可
